From 5cf231a346fb80d7945aa46e90186a068a3a001b Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Thu, 14 Jul 2011 11:55:35 -0700 Subject: hwmon: (pmbus/adm1275) Add support for ADM1276 ADM1276 is mostly compatible to ADM1275, with added support for input power measurement. Add support for it to the ADM1275 driver.
